ae apparently the only difference between the type and its 
variety is one of color this is generally so distinctive that it seems 
to deserve varietal recognition. The bright yellow form may 
blossom somewhat later than O. hispidus. Our no. 2911 secured at 
Corral the last of June has white flowers and at that time the 
variety tenuis was not found. Upon our return, Aug. 15, we col- 
lected the variety in the same field where the typical white form 
was abundant on June 27. Constant technical differences of 
corollas and seeds, however, have been sought in vain. 
PEDICULARIS GROENLANDICA Retz. Although Piper as long ago 
as 1901 suggested in Mazama ii. 100 that this species in typical 
form was confined to northeastern North America neither the 
“* Flora of Colorado ”’ nor the Coulter-Nelson Manual include the 
variety surrecta (Benth.) Piper, l.c. In their Flora of the North- 
west Coast Piper and Beattie have taken up Bentham’s species. 
Unfortunately for this treatment, typical P. groenlandica has been 
found in the Rocky Mountains and moreover there are some col- 
lections which are exactly intermediate between the western and 
eastern forms. In general, however, collections from the West 
have a very dense inflorescence and galea 10-15 mm. long, while 
specimens from Labrador all exhibit a rather open spike and a 
somewhat shorter galea (5-8 mm.). But proceeding westward 
across Canada there occur forms which, although possessing the 
short galea of the northeastern plant have the dense spike of the 
Rocky Mountain variety, and occasionally a Colorado collection 
exhibits a loosely flowered inflorescence when the galea is over one 
em. long. The really fundamental difference, therefore, between
